Description

CVE-2026-116327 is a vulnerability in PostgreSQL where sensitive information can be inferred by a database user through missing authorization checks in security_barrier view processing. This occurs when a leaky function is applied to a CASE test value or internal parameter that indirectly represents a protected column. Versions prior to 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
